Typeorm query fails when a relationship is added

Question

Hi guys I am using medusajs / typeorm and currently I am facing an strange problem, using the same repository to retrieve some data, works perfectly when no relationship is added, but when eager is added or relations added to the repository give an strange error:

Here is the files:

• Models:

import { Column, Entity, OneToMany, ManyToOne, JoinColumn } from "typeorm"
import { BaseEntity } from "@medusajs/medusa"
import { QuantityConstraint } from "../types/quantity-constraint"
import { ModifierOption } from "./modifier-option"
import { ProductVariant } from "./product-variant"

@Entity()
export class ModifiersGroup extends BaseEntity {

    @Column()
    title: string;

    @Column({  nullable: true })
    subtitle: string | null;

    @Column({  nullable: true })
    description: string | null;

    @Column({ type: "int", nullable: true })
    rank: number | null;

    @Column({  nullable: true })
    image_url: string | null

    @Column({ type: "bool", default: false})
    is_disabled: boolean

    @Column({ type: "simple-json", nullable: true })
    quantity_info: QuantityConstraint | null

    @OneToMany(() => ModifierOption, (modifierOption) => modifierOption.group, {
        cascade: true,
        eager: true
    })
    options: ModifierOption[]

    @ManyToOne(() => ProductVariant, (productVariant) => productVariant.modifiers_groups)
    @JoinColumn({ name: "variant_id", referencedColumnName: "id" })
    variant: ProductVariant
}

import {
    Column,
    Entity,
    ManyToOne,
    JoinColumn
} from "typeorm"
import { BaseEntity } from "@medusajs/medusa"
import { ModifiersGroup } from "./modifiers-group";
import { MoneyAmount } from "./money-amount";
import { QuantityConstraint } from "../types/quantity-constraint";

@Entity()
export class ModifierOption extends BaseEntity {
    @Column()
    title: string;

    @Column({ nullable: true })
    subtitle: string | null;

    @Column({ nullable: true })
    description: string | null;

    @Column({ type: "int", nullable: true })
    rank: number | null;

    @Column({ nullable: true })
    image_url: string | null

    @Column({type: "bool", default: false})
    is_disabled: boolean

    @Column({ type: "simple-json", nullable: true })
    prices: MoneyAmount[]

    @Column({ type: "simple-json", nullable: true })
    quantity_info: QuantityConstraint | null

    @ManyToOne(() => ModifiersGroup, (modifiersGroup) => modifiersGroup.options)
    @JoinColumn({ name: "modifiers_group_id", referencedColumnName: "id" })
    group: ModifiersGroup
}

• Repository:

import { FindOptionsWhere } from "typeorm"
import { ModifiersGroup } from "../models/modifiers-group"

import {
    dataSource,
} from "@medusajs/medusa/dist/loaders/database"

export const ModifiersGroupRepository = dataSource
    .getRepository(ModifiersGroup)
    .extend({
        async retrieveOneByVariant(variantId: string): Promise<ModifiersGroup | null> {
            return this.findOne(
                {
                    where: {
                        variant: { "id": variantId }
                    }
                }
            )
        }
    })

export default ModifiersGroupRepository

I tried, with eager on the model as is now, also adding relations: { options: true} in the repository, same error.
